I. Product Overview
The long arm for excavators is a crucial attachment designed specifically for excavators. By extending the working radius, it breaks through the limitations of conventional excavation scope. It can be widely applied in complex working conditions such as river dredging, high - rise building demolition, deep pit operations, and bridge construction, significantly expanding the excavator's operational capabilities and greatly enhancing construction efficiency.
II. Core Advantages
- Extra - long Working Radius: It breaks through the operation range limitations of traditional excavators, enabling long - distance and deep - depth operations. For example, some models' long arms can achieve a working radius of over 20 meters, easily reaching areas that are difficult for regular equipment to access, thus greatly expanding the operation range and improving construction flexibility.
- High Strength and Durability: Made of high - strength alloy steel materials like Q690 and HG785, and processed with advanced welding and heat - treatment technologies, it has excellent fatigue and fracture resistance. It can operate stably in high - intensity environments for a long time, effectively reducing equipment failure rates and maintenance costs.
- Flexible Adaptability: Customized design and adaptation solutions are provided according to different excavator brands, models, and diverse construction needs, ensuring a perfect match with excavators and giving full play to equipment performance. It also supports quick replacement of various accessories to meet different operation requirements such as digging, crushing, and grabbing.
- Efficient and Energy - saving Design: With optimized structural design and mechanical properties, it reduces energy consumption during operation, lowers fuel consumption, and improves energy utilization efficiency. While ensuring high - efficiency operation, it effectively reduces operating costs.
